Abstract
The invention features a hot melt adhesive compositions for disposable absorbent articles including from 5% by weight to 40% by weight of a non-modified styrenic block copolymer, from 0.5% by weight to 30% by weight of a modified styrenic block copolymer, from 30% by weight to 65% by weight of a tackifying agent, and from 10% by weight to 45% by weight of a plasticizer, wherein the hot melt adhesive composition comprises less than 5% by weight of a wax.
